Abstract

A fiber glass mat adapted to reinforce thermoplastic polymeric molding material is provided with improved flow properties in the molding process without sacrificing strength and without unduly increasing loft of the mat. The improvement is achieved by needling the mat from both sides with the number of needle punches per unit area on one side being greater than that on the opposite side.
